摘　　要：用 35Kev的 N+离子束注入茄子、蕃茄、辣椒等种子 ,进行诱变处理。通过田间种植对照分析 ,茄子比对照增产 2 5.0 %～ 57.9% ,发病率仅在 1 .89%～ 4.62 % ,变异果大 ,果脐呈带状、拉长 ,变异明显。离子束注入的加工蕃茄比对照早熟 2 0天 ,产量可提高 2 2 .4% ,蕃茄红素等品质因素经检测都有提高 ,当代效应十分明显。辣椒经离子束注入后 ,平均出苗率比对照提高 8.0 % ,显著提高了疫霉病的抗病性 ,死病率仅 38.6% ,比对照死病率 89.7%下降了 51 .1 % 。The seeds of Aubergine,Tomato and Hot Pepper are subjected to the injection of 35 kevN + ion mutation. Analysis of field plantation reveals that Aubergine increase production by 25.0%-57.9% and incidence rate of disease is only 1.89%-4.62%, the fruit navel grows larger, longer and into the shape of belt .Tomato subjected to ion implantion matures 20 days earlier andits production increases by 22.4%. Qualities such as lycopene are improved also. The effect of present age is very evident. After N + ion injection, the average germination rate of Hot Pepper increases by 8.0% and the resistance to disease of phytophthora capsici Leon also see some improvement. Fatality rate dropps by 51.1% to 38.6%. The study shows some potential to solve permanently hot Pepper's disease resistance problem, which have troubled the agriculture industry for many years.
